The turntable lower connecting plate 10 is provided with a plurality of rubber support columns 6 with steel balls and a lower rotating element 8 with steel balls. A rotating shaft fixed disk 5 is also installed on the turntable lower connecting plate 10. The turntable lower connecting plate 10 is connected to the turntable upper connecting plate assembly 4, and a lock 105 is welded below the turntable upper connecting plate assembly 4.

[0036] In this embodiment, the turntable is divided into an upper and a lower part, which is composed of a locking assembly 7, a connecting assembly and a structural reinforcement sheet metal part. The upper part of the turntable includes a fixed plate 2 on the rotating shaft, an upper rotating element 3 and a connecting plate assembly 4 on the turntable, a fixed plate 5 in the rotating shaft, a rubber support column 6, a locking assembly 7 and a lower rotating element 8. The lower part of the turntable includes a locking assembly mounting plate 11, a locking assembly return spring 12 and a turntable mounting and fixing assembly 14. A rotating element is provided between the upper and lower parts of the turntable. The rotating element includes an upper rotating element 3 and a lower rotating element 8. A steel ball is clamped on the rotating element to maintain sufficient sliding force while stabilizing the gap. The rotating element is then welded to the locking assembly mounting plate 11 through the fixed plate 5 in the rotating shaft. The rotating element clamps the upper and lower parts of the turntable and rotates them on the locking assembly mounting plate 11.

[0037] The turntable mounting fixing assembly 14 is connected to the bottom of the locking assembly mounting plate 11 by bolts, and a locking assembly 7 is fixed to each of the two sides above the locking assembly mounting plate 11 through the recoil spring hanging rivet 106 and the limit rivet 110. The locking assembly mounting plate 11 also welds the unlocking hook 109 on both sides, and hangs the locking assembly recoil spring 12, and the turntable lower connecting plate 10 is fixed in the middle by bolts; a number of rubber support columns 6 with steel balls are installed on the turntable lower connecting plate 10, and a lower rotating assembly 8 with steel balls is set, and the fixed plate 5 in the rotating shaft is installed, and then the turntable upper connecting plate 101, the expansion mounting plate 102 and the turntable upper connecting plate assembly 4 assembled with bolts and welded with the turntable upper connecting reinforcement plate 103 are set thereon, and a lock column 105 is welded under the connecting plate assembly 4. Finally, the upper rotating element 3 is set, and all the above components are installed as a whole through the fixed plate 2 on the rotating shaft;

[0038] The turntable in this embodiment is divided into two parts, upper and lower, and is composed of a locking component 7, a connecting component and a structural reinforcement sheet metal. A rotating element is provided between the upper and lower parts of the turntable. A steel ball is stuck on the rotating element to maintain sufficient sliding force while stabilizing the gap.

[0039] When the turntable needs to be adjusted, the unlocking hook 109 is pulled to both sides, and the locking sheet metal 107 slides to both sides under the joint action of the unlocking hook and the assist spring. After sliding a certain distance, it pushes the locking support block 104 to continue sliding to both sides until it disengages from the lock column 105 position to complete the unlocking action. At this time, the turntable can be rotated 180° clockwise or counterclockwise. When it rotates 180° to the locked position, the unlocking hook 109 is released, and the locking sheet metal 107 and the locking support block 104 slide inward under the action of the locking assembly return spring 12, and jam the lock column 105 to complete the locking.

[0040] For further information, see Figure 2 and Figure 3The turntable upper connecting plate 101, the expansion mounting plate 102 and the turntable upper connecting reinforcing plate 103 are assembled by bolts.

[0041] In this embodiment, the turntable upper connecting plate assembly 4 includes a turntable upper connecting plate 101, an expansion mounting plate 102 and a turntable upper connecting reinforcement plate 103, and the turntable upper connecting plate 101, the expansion mounting plate 102 and the turntable upper connecting reinforcement plate 103 are assembled by bolts.

[0042] For further information, see Figure 1 and Figure 2 An upper rotating element 3 is provided above the upper connecting plate assembly 4 of the turntable.

[0043] For further information, see Figure 1 and Figure 2 A fixed disk 2 on the rotating shaft is provided above the upper rotating element 3.

[0044] For further information, see Figure 1 and Figure 5 The turntable mounting and fixing assembly 14 includes a mounting plate 111, two lower reinforcement plates 112 and two side reinforcement plates 113. The two lower reinforcement plates 112 are arranged opposite to each other, the mounting plate 111 is arranged on the top of the two lower reinforcement plates 112, and the side reinforcement plates 113 are arranged on the outside of the lower reinforcement plates 112.

[0045] In this embodiment, the locking assembly mounting plate 11 is connected to the mounting plate 111 by connecting bolts 9 and the turntable lower fastening nut 13, thereby realizing the connection between the locking assembly mounting plate 11 and the turntable mounting fixing assembly 14; the turntable upper connecting plate assembly 4 is connected to the mounting plate 111 by connecting bolts 9 and the turntable upper fastening nut 1, thereby realizing the connection between the turntable upper connecting plate assembly 4 and the locking assembly mounting plate 11, wherein a rotating shaft fixed plate 5, a rubber support column 6, a locking assembly 7 and a lower rotating element 8 are provided between the turntable upper connecting plate assembly 4 and the locking assembly mounting plate 11, an upper rotating element 3 is provided above the turntable upper connecting plate assembly 4, and a rotating shaft fixed plate 2 is provided above the upper rotating element 3.

[0046] Furthermore, the rubber support column 6 with the steel ball and the locking support block 104 jointly maintain the stability of the locking position.

[0047] In this embodiment, the rubber support column 6 cooperates with the steel ball and the locking support block 104 to maintain the stability of the turntable in the locked position and prevent it from shaking left and right.

[0048] Furthermore, a stop point is provided on the locking assembly mounting plate 11, and the stop point is used to ensure that the turntable can only rotate 180°.

[0049] In this embodiment, the blocking point allows the turntable to rotate only 180°, and also enables the locking mechanism to complete locking more smoothly.

[0050] Example 2:

[0051] See also Figure 6 The size of the turntable is approximately 173mm×515mm×88mm. The difference between Example 2 and Example 1 is that the turntable mounting and fixing component 14 and the turntable connecting reinforcement plate 103 in Example 1 are structural reinforcement components and can be omitted when necessary, that is, the turntable of Example 2. Compared with Example 1, Example 2 reduces the weight of the turntable and reduces the cost.

[0052] The working principle and usage process of the present invention are as follows: when the turntable needs to be adjusted, the unlocking hook 109 is pulled to both sides, and the locking sheet metal 107 slides to both sides under the joint action of the unlocking hook and the assist spring. After sliding a certain distance, the locking support block 104 is pushed to continue sliding to both sides until it is out of the position of the lock column 105 to complete the unlocking action. At this time, the turntable can be rotated 180° clockwise or counterclockwise. When it rotates 180° to reach the locked position, the unlocking hook 109 is released, and the locking sheet metal 107 and the locking support block 104 slide inward under the action of the locking assembly return spring 12, and jam the lock column 105 to complete the locking.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
